I tried a lot of configurations and bios settings without succes.
If the WAN interfase is going down i have no internet acces and the led's of my wan nic is going off.
The lan interface is stable and working well.
I have a mainboard Jetway NF9HB with 4 nic's
How can i find and solve this problem.

update:
If i connect my firewall wan to my router (apple airport expres) the problem is gone.   :o
My wan is configured with DHCP.
How can I configurate my firewall WAN without my router?

update 2:
If i turn off Intrusion detection, problem is gone  :)
If i turn on Intrusion detection on my LAN (not on WAN), problem is gone  :)
If i turn on Intrusion detection on my WAN (not on LAN), problem is there immediatly >:(

Is this a bug or a hardware related issue?

That would be in Services: Intrusion Detection: Administration. Perhaps it would be a good idea to give details of your hardware and specifically the NIC device or if it's a VM and which type of hypervisor etc., etc.
